What's the best iOS app for blocking spam calls and protecting my phone from security threats?

Verizon Protect is designed specifically for Verizon customers seeking comprehensive mobile security. The app includes real-time scam detection that automatically identifies and blocks suspicious calls before they reach the user. For device protection, it offers security scanning that checks for malware and vulnerabilities, along with identity monitoring services that track personal information across the web. Users particularly appreciate the seamless integration with Verizon's network, which enhances call filtering effectiveness compared to third-party alternatives. Reviews indicate the interface remains straightforward, though some users note occasional false positives with legitimate calls being flagged. The app's free tier includes basic protection features, while premium subscriptions add identity theft insurance and extended monitoring capabilities. One limitation worth noting is that certain advanced features require maintaining an active Verizon wireless plan. For iPhone users primarily concerned with call security and basic device protection, Verizon Protect delivers reliable performance without complicated setup processes.
